Both services are now running and will start automatically on boot:
- phone-ap.service: Monitors WiFi and manages AP
- phone-web.service: Web server for configuration

How it works:
- If connected to WiFi: Access at http://yellow-phone.local
- If NOT connected: WiFi AP "yellow-phone-setup" will start automatically
  Connect to the AP at the same address http://yellow-phone.local

To check status use ./cli
